would
assign values
as follows:
A$ =
PECOS
B$= TEXAS
"GOOD MELONS"
C$
=
null string
If a
comma
is
inserted in the data
image
before
the
first
double
quote, c$
will
get the value,
good
melons.
These
are very simple examples
just to give
you
an
idea of
how
input works.
However,
there are
many
other
ways
to input data
—
different terminators,
different target variable types,
etc.
Rather than
taking a shotgun approach and
trying
to
cover
them
all,
we'll give a
generalized description of
how
input
works
and what
the terminating characters
and
conditions
are,
and
then provide
several examples.
When
basic encounters
a terminating
character,
it
scans
ahead
to
see
how many
more
terminating characters
it
can
include with
the
first
terminator. This ensures
that
basic
will
begin looking
for the next data item
at
the correct place.
The
list
below
defines the various terminating
sets
input#
will
look
for.
It
will
always
try to take-in the largest
set possible.
